I think internet shops has static ip.
hi ate maud. im not really an expert on computer but here's what the computer lab technician said in our school taught me. yeah i interviewed him lol.
in a computer shop it's either you set ip dynamically or static ip. for static ip, if you have 5 computers you assign ip to them one by one. example:
computer 1 = 192.168.1.190
computer 2 = 192.168.1.191
computer 3 = 192.168.1.192
computer 4 = 192.168.1.193
computer 5 = 192.168.1.194
so yeah, still each computer has unique ip. correct me if i'm wrong, i mean if our comlab technician was wrong
